如何在silverlihgt中使用右键

添加一个<TextBlock>到Page.xaml中

<UserControl x:Class="rightClick.Page"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Width="400" Height="300">
<Grid x:Name="LayoutRoot" Background="White">
<TextBlock x:Name="MyField">Right click please.</TextBlock>
</Grid>
</UserControl>

  在页面中设置silverlight的参数Windowless="true"

<asp:Silverlight ID="Silverlight1" runat="server" Height="480px"
MinimumVersion="2.0.30523" Source="~/ClientBin/rightClick.xap" Windowless="true" Width="640px" />        <object data="data:application/x-silverlight," type="application/x-silverlight-2-b2" width="100%" height="100%">
<param name="source" value="ClientBin/rightClick.xap"/>
<param name="onerror" value="onSilverlightError" />
<param name="background" value="white" />
<param name="Windowless" value="true" />
<a href="http://go.microsoft.com/fwlink/?LinkID=115261" style="text-decoration: none;">
<img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style: none"/>
</a>
</object>

  最后修改Page.xaml.cs页面的代码

  新建立一个ContextMenuInterceptor类.这个类是用来处理页面中“OnContextMenu”事件的.在用到HTMLPage对象你需要引入System.Window.Browser命名空间.
  在调用e.PeventDefault()方法后,将会取消右键点击事件.所以silverlight不会捕捉到它.
  在这里我们已经成功的拦截了右键点击事件,做我们想做的任何事情了.;)

}
private void OnContextMenu(object sender, HtmlEventArgs e)
{
TextField.Text = "Right Clicked Blocked at " + e.OffsetX + "," + e.OffsetY;
//Cancels the event if it is cancelable.
            e.PreventDefault();
}
}
}
